October 15, 2020: The largest hybrid lead-acid/lithium battery energy storage system in Poland has begun a full-scale demonstration, project partners New Energy and Industrial Technology Development Organization (NEDO), Hitachi, Showa Denko Materials and Sumitomo Mitsubishi Banking Corporation said on October 2.

The project is also supported by Poland’s Ministry of Climate and other Polish project companies, and “aims to contribute to further integration of renewable energy in Poland by achieving secure power grid operation while minimizing investment costs for power transmission equipment at the same time”.

The lithium batteries have an output of 1MW and the lead acid batteries an output of 5MW and a storage capacity of 30MWh. The input is generated by the Bystra wind farm in northern Poland.

The demonstration, which aims to validate and prove the effectiveness of the system’s ability to alleviate short-term fluctuations in wind power generation and to provide reserve power, began on September 25.

“The system will also be used to solve issues with transmission and high voltage distribution line overloads during a power grid failure,” said a statement.

A successful demonstration will allow the partners to consider developing similar business models further afield, the statement said.
